Asked By 10 points N/A Posted on -

Exchange 2010 DAG – Error Message


You are facing this error message because of adding a new node via Exchange DAG. The Forest usually seeks for older values of DAG (host). To get fix this issue, point to backup windows and select Microsoft Database base Available Group. Now select Manage Forest, find the old Forest Entry and add a new DAG name. This will surely help you get fix the issue.

Exchange 2010 DAG – Error Message


Hello Evelyn,

Cause of the error:

In the event that the exchange DAG was rebuilt,  or the node was replaced using a different node, then the issue you are getting is as a result of backup exec Forest entry still having access to the old DAG entry of the host.

The following is the resolution to it:

  • You will need to locate the backup window.
  • You will then right click on the Microsoft Exchange Database base Availability Group.
  • Next you will choose manage forest.
  • And then you will get rid of the old forest entry.
  • After that you add a new DAG name.
